Mobile Unlocked has put together an interesting interactive tool that shows contract-free iPhone prices around the world, both in absolute terms and as a percentage of GDP. There are four countries where an iPhone sells for around 20 percent of the average annual income: Philippines (18%), Jordan (18.2%), Vietnam (19.8%) and India (22.3%).

Qatar – one of the richest countries in the world – has the lowest percentage, at less than 0.8%, while the USA comes in at just under 1.4% and the UK at 2.4%.

Cheapest in cash terms is the USA at $707, most expensive is Jordan at $1091. In the US, of course, most of the true cost of the iPhone is a disguised part of your monthly contract fee.
